Acquired deformity of other specified site

This code signifies a non-congenital structural abnormality or malformation affecting a specific body site not otherwise classified. These deformities are typically the result of injury, disease, or other external factors occurring after birth, leading to an altered shape, size, or position of a body part.

Apply this code when documentation clearly indicates an acquired deformity of a specific anatomical location (e.g., nose, ear, breast, or other specified organ/structure) that isn't covered by more specific ICD-9 codes. This is appropriate when the underlying cause of the deformity is known and has been treated or is no longer active, and the deformity itself is the primary focus of care.

• Ensure the documentation specifies "acquired" and not "congenital" to differentiate from Q-codes.
• Always look for a more specific code first; this is a residual category for deformities of "other specified sites."
• Code the underlying cause of the deformity if it is still active and relevant to the current encounter.
